That's the default behavior if you don't change the tabs setting in Safari (if you change, try hold down Command or Ctrl key plus Alt key and then click on the link).

这是默认行为，如果你不改变的标签，设置在Safari （如果你改变，请尝试按住指挥或CTRL键加上ALT键，然后点击链接）。

Shining light selectively on one eyespot changes the beating of the adjacent cilia. The resulting local changes in water flow are sufficient to alter the direction of swimming, computer simulations of larval swimming show.

计算机模拟幼虫游动图像显示：闪烁的光线在眼点上分布不均，这样就改变了临近纤毛拍打海水的幅度，由此引起的海水浮动足以改变生物游动的方向。

In this paper,the existing problem of traditional method to deal with the availability matrix in the theory of data amalgamation are analyzed,and a algorithm of real time fusion process for echo association point aggregation is put forward.

摘 要：分析了数据融合理论中传统有效矩阵处理方法存在的问题，提出了一种随回波密度的改变而改变的相关点集实时融合处理算法。

At 8 weeks, the liver in the experimental group developed purple, seems wrapping with millets. Pathological sections showed punctiform or lamellar cellular necrosis, inflammatory cell infiltration around liver canaliculus, displaying early symptoms of liver fibrosis. At 12 weeks, the liver looks gray, seems wrapping with many types of millet.

实验组8周时，肝脏呈暗紫色，表面有轻微粟粒样改变，病理切片示：肝细胞点状及点灶状坏死，汇管区炎症细胞浸润，呈早期纤维化症状。12周时，肝脏呈灰褐色，有较明显粟粒样改变。

By the cooperation of 8-MOP/UVA, the photoaging-characteristic biological markers of the dermic fibroblasts in vivo and in intro were changed as follows:① with a permanent switch of mitotic to stably postmitotic phentypes, fibroblasts displayed growth suppression and morphological changes of cell senescence;② increasing expression of SA-β-galactosidase;③ increasing expression of p16 protein;④ continuous up-regulation of mRNA of MMP-1 and MMP-3, while the protein of TIMP-1 was only slightly induced;⑤ high levels of the 4977bp deleted mtDNA accumulated in dermis and cultured fibroblasts, and large accumulation of a A→C base transversion of 414 position of 〓 of human mtDNA control region for replication of cultured fibroblasts also.

2.8-MOP/UVA作用下，体内外真皮成纤维细胞生物学特性出现具有光老化特征性的改变：①细胞由具有分裂活性的分裂表型转化为不具有分裂能力的分裂后表型，形态学出现细胞衰老的相应改变；②SA-β-Gal表达增加；③p16蛋白表达增加；④MMP-1、MMP-3 mRNA持续表达而TIMP蛋白表达仅被轻微诱导；⑤mtDNA 4977bp缺失大量累积，培养成纤维细胞mtDNA复制控制区〓片段414碱基迅速出现大量A→C的点突变。

Out of all P16 gene changes,4 were dot mutation,2 were deletion and 1 was heterozygous.

结果16例胰腺组织标本中有7例检测出存在着P16基因的改变，4例标本为点突变，2例标本为缺失型改变，还有1例患者存在着野生型与缺失型同时存在的杂和状态。

It is difficult to be simulated and analyzed due to the excessive surfaces, complex structure and locomotory parts in zoom lens. All the transmission planes taken as the partial reflection and partial transmission planes were simulated with ASAP（advanced system analysis program）and the stray rays on "dangerous surfaces" which easily generate the ghost images in zoom lens were analyzed. Based on it, the zoom lens was optimized and the quality of image was improved by changing the curvature and refractive index of the second reflection planes.

利用ASAP软件模拟每个透射面作为部分透射、部分反射的表面，对变焦光学系统非轴上光进行分析，模拟出变焦系统的光学元件表面和光机内壁，实行实际光线追迹，然后以像面为研究对象，进一步实施实际光线追迹，模拟出全部散射光在像面上的能量分布，找出鬼像形成的原因，并在此基础上通过改变二次反射所在面的曲率或改变所在面的折射率两种方法对变焦光学系统进行优化，减小鬼点数目，以提高系统的成像质量。

电路板元器件绘制系统主要完成了使用鼠标拖拽、鼠标点按的方式绘制电路板上各种常见的元器件图形；编辑电路板上元器件图形的位置；编辑元器件图形的颜色；不失真的对器件图形进行放大和缩小；编辑元器件图形的线型；编辑电路板上各个器件的物理属性(比如电阻的阻值大小、电容的容量大小、额定电压等)；复制已经绘制出的电路板上的器件；粘贴剪贴板上的器件；删除单个或多个已经绘制出的器件图形；同时改变多个器件图形的位置；改变绘制区内各个元器件的z order顺序，也就是可以将层叠在一起的图形置前或置后；把绘制的电路板器件图保存到指定文件中；能打开、查看和修改保存的电路板器件图；打印电路板器件图。

Objective To establish rat model with polycystic ovary with two different methods:testosterone plus human chorionic gonadotropin and progestogen plus HCG,compare the rat models induced by testosterone plus HCG with the patients with polycystic ovary syndrome in the aspects of ovarial morphous and gonadal hormone,and investigate whether testosterone with HCG is the effective method to establish rat model with polycystic ovary syndrome,than compare two methods(T+HCG and P+HCG)finally to draw a conclusion if there are any difference or similary between the two methods and which one is more ideal and convenient.Methods 60 SD female rats of 23 days were divided into three groups in random.

目的 本实验用睾酮联合绒毛膜促性腺激素及炔诺孕酮联合HCG两种方法分别建立多囊卵巢大鼠模型，将模型鼠的卵巢形态及血清激素方面改变与人类多囊卵巢综合征的病理改变加以比较，探讨睾酮联合HCG是否是建立多囊卵巢大鼠模型的有效方法，并比较两种造模法是否存在异同点，判断哪一种造模方法更为理想及简便有效。

Symptoms of central nervous system dysfunction: Blurred vision,scotomata, altered mental status, severe headache

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
